Have you tried using this? I have a suspicion you may end up with a bunch of head components that could cause bugs since "During rendering, Turbo Drive replaces the contents of the element and merges the contents of the element." So we just keep adding components to head without ever removing them and the components that are present depends on how the user moves through our site.

Yeah it's in production right now for Hotjar.

But hotjar should be on every page, correct? Imagine I add a component to scroll the page to the top, then on a different page I add a component to scroll to the bottom, both will exist in the head until a refresh occurs since the head is merged. I can dive in a little deeper and run some tests to see if my concern is valid. If it is, we could make some hard to diagnose bugs in the future.

Yeah I guess this is meant to inject HTML on every page. I thought Turbo updates head if it changes, but maybe not.

It does update head, but it merges the existing head and the new head together. https://turbo.hotwired.dev/handbook/introduction#turbo-drive%3A-navigate-within-a-persistent-process we have hit some hard to diagnose bugs with this before. You have the ability to refresh on head change, but that removes the purpose of turbo.

I see. Okay makes sense, this feature could be a bit dangerous, got it. Maybe a set of pre-built head templates would be better? And allow our main app to pick one or inject its own?

Do we want hotjar on every page. As of now if the user goes to postgresml.org then to postgresml.org/blog hotjar is in the header, but if the user goes directly to postgresml.org/blog, hotjar is not present. We can add hotjar to cloud2 header component to fix this.

We do want it on every page, but I wanted to avoid to add it to the open source code, since we don't want our open source users to accidentally load the hotjar code.

If you add it to the cloud2 extend_header, open source will never see it, but it will be on every page in the production site. putting it here should be fine https://github.com/HyperparamAI/hypercloud/blob/71bd5877c6e1f87b3d59afd488ff42ecfee58960/cloud2/src/components/layouts/extend_head/template.html#L35

Ah TIL, thanks. That solves my issue.
